代码42行关于unsigned占用字节数的疑问
42行的代码 for (i = 0; i < 2 * size - 1; ++i)
如果是遍历所有longest中数据的话，应该是 ：
for(int i=0; i < size * 2 * sizeof(uint32_t); i++)
我的理解是，在生成内存数据的时候使用了self = (struct buddy2*)ALLOC( 2 * size * sizeof(unsigned));
unsigned假如占4字节，所以42行代码直接写成for (i = 0; i < 2 * size - 1; ++i) 我感觉会有些问题。
fixsize这个函数向上取整的时候，如果size本身已经是2的幂，为什么还要向上转换？
buddy2_size越界
buddy2_size函数中
for循环判断条件加个index >= 0
